Class StringPool

  • public final class StringPool
extends java.lang.Object
    Utility to normalize String instances in a way that if equals() is true for two strings they will be represented the same instance. While this is exactly what String.intern() does, this implementation avoids VM specific side effects and is supposed to be faster, as neither native code is called nor synchronization is required for concurrent lookup.
